En bloc (collective sale)
What is en bloc (collective sale)?
An en bloc, or collective sale, is when the owners of a strata development such as a condominium sell the whole development together, usually to a developer who will redevelop the land. It currently needs written consent from owners holding at least 80% of the share values and strata area, or 90% for developments under 10 years old.

How an en bloc works
In a strata development, each owner owns their own unit plus a share of the common property and land. An en bloc sale lets the owners sell the entire development as one, which is often worth more to a developer than the units are worth separately.
Because a sale needs a high level of agreement but not unanimity, the law sets consent thresholds and a process to protect owners who disagree.
- Form a collective sale committee. Owners call a general meeting to elect a committee to run the sale.
- Sign the collective sale agreement. The committee sets a reserve price and the method for splitting the proceeds, and owners sign the agreement.
- Reach the consent threshold within the signing window.
- Sell the site, usually by public tender.
- Apply to the Strata Titles Board if not every owner has agreed. Objecting owners can be heard before the sale is approved.
- Complete the sale and distribute the proceeds.
Consent thresholds: today and under the new law
| Age of development | Threshold today | Under the 2026 amendments |
|---|---|---|
| Under 10 years | 90% | 90% |
| 10 to 39 years | 80% | 80% |
| 40 to 59 years | 80% | 70% |
| 60 years and above | 80% | 65% |
The 2026 amendments also:
- cut the time to collect signatures from 12 months to 6
- extend the restriction period after a failed attempt from 2 years to 3
- raise the support needed to form a collective sale committee from 20% by share value (or 25% by number of units) to 35%
Sales that have already started collecting signatures continue under the current rules. Owners of developments aged 40 years and older that are mid-process may be able to switch to the new framework.
Example
A 45-year-old condominium is considering an en bloc.
| Scenario | Consent needed |
|---|---|
| Today | 80% |
| After the 2026 amendments take effect | 70% |
Common mistakes
- Forgetting Seller’s Stamp Duty. Owners who bought recently may owe SSD on their share of the sale.
- Not planning the next home. Owners often need to buy a replacement home, which brings BSD and possibly ABSD.
- Signing without reading the apportionment. How proceeds are split varies between agreements.
Frequently asked questions
Can I be forced to sell in an en bloc?
If the consent threshold is reached, the sale can go ahead without every owner's agreement. Owners who object can raise their objections when the application is heard.
How is the sale money split?
Proceeds are shared among owners using a method set out in the collective sale agreement, usually based on share value, strata area or both. Check the agreement before you sign.
Do I pay Seller's Stamp Duty in an en bloc?
Yes, if you bought your unit within the SSD holding period. IRAS says this applies whether or not you consented to the sale.
